Who will risk experimenting with SAXITOXIN? It is 1000 times more toxic >than a typical synthetic nerve gas such as sarin. It was used by CIA in >1950's as a suicide capsule. President Nixon ordered entire stock of of >SAXOTOXIN to be destroyed. > There are plus point to SAXOTOXIN, it has been used in medical research. > Checking on the structure of Saxitoxin in the Merck Index reveals that it >> has a most interesting architecture. Three terminal NH2 groups, an ether >> linkage and a ketone. Its stable in acid solution but decomposes rapidly in >> alkaline media. It looks like very good food for anaerobic bacteria and I >> suspect would decompose rapidly in the presence of acetogens and >> methanogens. Try a sample of digested sewage sludge (anaerobic) culture with >> some milk for a few days at 35 Celsius until gas is produced.
